I don't think it's a browser bug, I think it's a problem with the WebGL renderer in Construct 2. If you look in Chrome's console this error comes up:'uniformMatrix4fv: location is not from current program'I found why this error was happening and fixed it for the next build - since it correlates with the problem happening, I think that means this issue should be fixed in the next build. Let me know when r101 is out if it's better.
